Unit 6Section BJudge by AppearancesA standard criticism of sociological research is that it goes to great lengths to prove what most people with common sense already know. Without exactly taking sides for or against that criticism, I want to describe a sociological exercise that might seem to validate it—except that, for me and a classmate (and maybe for some who read this account), the experience made a common claim come alive.During spring break from a local college, my friend and I went downtown to shop. First, however, we made ourselves virtually unrecognizable to our friends and even to our families. We wore clothing slightly inappropriate for the weather, clean but not ironed, clearly not the styles worn by most visitors to the area. We carried plastic bags of nameless possessions. Both of us were slightly untidy. My friend wore a faded cotton shirt over a T-shirt and a wrinkled skirt over sweat pants. I wore a wool hat that concealed my hair and an unfashionable coat and glasses with sunshades that clipped on.The aim was to look like street people and to observe what difference that made in the way other people responded to us—whether the appearance of poverty would invite prejudice on us. We were also prepared to act out some mildly unusual behaviors that might speak of some emotional problems, without appearing seriously disturbed or dangerous. As it turned out, there was no need for dramatics; people turned us off or tuned us out on the basis of appearance alone.Our first stop (after parking our cars near the railroad tracks) was in the bargain store of a local charity, where we politely asked access to a bathroom and were refused. Next we entered the lobby of a large hotel, where we asked for a coffee shop and a bathroom. The doorman said, "You must go to the twentieth floor." We weren't up to trying our act at an exclusive restaurant, so we wandered around the first floor and left. From there we went to a second-hand shop, where we more or less blended with the customers, and then on to the upper-scale stores and coffee shops during the lunch hour.It was prejudice time. Some of the children we encountered stared, pointed, and laughed; adults gave us long, doubting looks. Clerks in stores followed our track to watch our every move. In a lunchroom a second assistant hurried to the side of the cashier, where they took my $2 check without asking for ID; it seemed worth that price to have us out the door. At one doorway a clerk physically blocked the entrance apparently to discourage our entry.We had money to cover small purchases, and, apart from wearing downscale clothing, we did nothing in any of these settings to draw attention to ourselves; we merely shopped quietly in our accustomed manner. At one establishment we did blow our cover when we ordered French rolls with two special coffees; that may have been too far out of character for "bag ladies". Elsewhere we encountered ribbing, imitating, lack of trust, and rude stares.So what did we learn? Mostly what we expected, what everybody knows: People judge by appearances. Just looking poor brings with it prejudice, accompanied by removal of much of the social grace most of us take for granted. Lacking the culturally acceptable symbols of belonging in this setting, we became, to a degree, objects, with less inherent dignity as persons.There was, however, one surprise—more accurately, a shock. It became clear most strongly at the shop I mentioned earlier, the one where a clerk conspicuously positioned herself in theentrance on seeing us. I had just noticed the place and had turned to my companion, saying, "I've never seen this store. Let's go in." She looked at me with alarm: "You're not really going there, are you?"I knew what she meant and shared her feeling. The place felt out of bounds for us. In a very few hours, we found ourselves accepting and internalizing the superficial and prejudiced judgments of ourselves that prevailed among the people we met; we catalogued ourselves. Undoubtedly, it's a good lesson to learn, maybe especially for sociologists.(Words: 703)。

Book II Unit 6 A Woman can Learn Anything a Man Can男人学得会的，女人也学得会Carolyn Turk1. When I was a kid, everything in my bedroom was pink. I have two sisters and we had a complete miniature kitchen, a herd of My Little Ponies and several Barbie and Ken dolls. We didn't have any toy trucks, G.I. Joes or basketballs. We did have a Wiffle-ball set, but you would have been hard-pressed to find it in our playroom. Tomboys we weren't.1. 我小时候卧室里的每样东西都是粉红色的。

我有两个姐妹，我们有一个一应俱全的微型厨房，一群各种颜色的小马驹，还有好几个芭比和凯恩玩具娃娃。

我们没有玩具卡车，没有玩具大兵，也没有篮球。

我们确实有一套空心棒球，但是很难在我们的游戏室找到，毕竟我们不是假小子。

2. So some people may find it ironic that I grew up to be a mechanical engineer. In fact, I am the only female engineer at my company. In order to get my college degree, I had to take a lot of math and science classes. I also had to work with a team of students as part of a national competition to convert a gas-guzzling SUV into a hybrid electric vehicle--that's where I learned how to fix cars. I'm proud to say that I got A's in all my classes, including multivariable calculus and differentialequations. I've always been pretty good at math and design, but I didn't understand where that could take me. I was expected to go to college, but no one ever told me I'd make a good engineer someday.2. 因为如此，有些人对我长大后成了一名机械工程师也许感到出乎意外。

第六单元妇女半边天课文A????有些妇女何以能既做一份全职工作又能兼顾家庭的责任，并仍有余暇做其他事情?艾德丽安·波珀渴望能像她们一样，但又怀疑这会不会是一个根本无法实现的梦想。

我要买下布鲁克林桥艾德丽安·波？????不久前，我收到母校一份校友简报。

里面有一条是关于一个老同学的消息：“凯特·L在俄克拉荷马大学兼职任教，并任县高中校长助理。

她正在利用业余时间完成博士论文以及两本著作的最后定稿，同时她仍有时间与女儿们一起打网球、骑马。

”这条短讯中有四个字令我心神不安：业余时间。

有位朋友说，要是我对这一报道里的一切都信以为真，那她在布鲁克林还有一座桥要出售给我呢。

????朋友的打趣一针见血。

我多蠢啊!于是我打定主意，不再去想凯特那些不可思议的成就，以后看到类似报道也不要轻易相信。

????可是，就像节食者一时软弱竟把整盒饼干吃个精光一样，我发现自己的决心也有动摇之时。

每当不坚定时，我就在报刊上到处搜寻，贪婪地阅读一篇又一篇的成功故事。

我最喜欢的女强人有＼一位政治家的女儿，她在照料一个两岁幼儿与一个新生儿的同时读完了法学院，同时还经营着一家公司；一位开业儿科医师，她自己有十个子女还有一位电视主持人，她是两个学龄前儿童的母亲，还在攻读硕士学位。

然而，有一天我真的与一位女强人面对面相逢。

去年圣诞节前，我因工作需要来到一家全国性公司女总裁的办公室。

如同其他女强人一样，她有丈夫，两个孩子，还有一处据说是纤尘不染的公寓。

她的生活安排得如瑞士表一般精确。

由于我本人的计划安排很少成功，她的成就既令我惊讶不已，又使我深感内疚。

????那天，她办公桌后面的架子上放置了至少一百罐草莓酱，上面扎着鲜艳的红格缎带。

这些果酱是总裁和她的孩子们一起制作的，罐子也是他们一起装饰的，她准备把果酱送给员工及来访的客户。

????我不由得惊问，她从哪儿抽出时间完成如此令人钦佩的假日工程?我真不该多此一问。

答案听上去相当熟悉：业余时间。

第一单元发动机分类及工作原理课文A发动机的分类所有的汽车发动机都是内燃机（ICE),就是将燃油在气缸内进行燃烧，并将燃烧产生的膨胀压力转变成转动力，用来驱动汽车。

所以说，发动机是动力源, 并被认为是汽车的心脏。

汽车发动机根据工作方式分为往复式发动机和转子发动机：报据发动机燃烧的燃料分为汽油机和柴油机：根据发动机的气缸数量和气缸排列方式分为直列发动机、V型发动机、对置式发动机和W型发动机。

往复式发动机和转子发动机往复式发动机也称为活塞式发动机。

该发动机采用一个或多个活塞在气缸内上下运动或前后运动，将压力转变为转动动能传递给汽车驱动轮（见图1-1)。

往复式发动机广泛应用现代汽车上。

转子发动机是于1954年研发出来的。

如图1-2所示，在该发动机中，有个三角形的转子在燃烧室内旋转。

膨胀气体使转子旋转，产生动力并排出废气。

转子发动机没有活塞和气门等往复部件。

转子发动机产生马力大、无振动，但其燃油消耗比往复式发动机要高。

汽油机和柴油机汽油机以汽油作为燃料。

采用火花塞点燃缸内的可燃混合气，产生动力使汽车行驶，如图1-3a所示。

汽油机也称为火花点燃式发动机。

该发动机的特点是转速高，运行平顺，结构简单，重量轻，成本低。

几乎所有轿车都采用汽油机。

柴油机以柴油作为燃料。

该发动机的工作原理足通过压缩缸内的空气使其升温，冉使喷油嘴喷入的柴油燃烧，产生动力驱动汽车(见图1-3b)，所以也称为压燃式发动机。

柴油机要比汽油机的动力更强劲，燃油经济性更好。

常见于所有的大型货车、客车和部分轿车上。

直列发动机，V型发动机，水平对置式发动机，W型发动机通过气缸数最和气缸排列方式可以识别发动机结构。

当今所有的紧凑型轿车都配有4缸发动机，一些中型级轿车配有6缸发动机，大型轿车配有8缸或12缸发动机。

在多气缸发动机上，气缸通常以四种排列方式中的一种排列，有：直列式、V型、水平对置式和W型。

直列式发动机中的气缸按直线排列，采用一个气缸蓝。

几乎所有4缸发动机都采用该种排列（兄阁1-4)。

Unit 6 Women, Half the SkyText A A Woman Can Learn Anything a Man Can1.(Para. 2) ironic: adj. humorously sarcastic or mocking*我如此拼命要守住的这个秘密，却被他们这么漫不经心的对待.(=How ironic is it to have something I tried so desperately to keep secret treated so casually.)* It is sadly ironic that in these modern times it still takes weapons to prevent war. CF: sarcastic, satiric & ironic这三个词都是形容词, 都有“讽刺的”之意。

sarcastic 指运用讥讽的、嘲笑的（方法、方式）。

例如：Must you always be so sarcastic when I ask you anything?每当我问你时，你有必要总是这样嘲笑吗？satiric 指喜好讽刺的、含有讽刺的。

例如：Gulliver’s Travels is a satiric book.《格利弗游记》是一部讽刺小说。

ironic 指讽刺的、具有讽刺意味的。

例如：It was ironic that he should have been invited to play for the Scotland team on the very day that he broke his legs.具有讽刺意味的是他正好在跌断腿的那一天收到了要为苏格兰队踢球的邀请。

2. (Para. 2) convert: vt. change the nature, purpose, or function of something* The room was converted from a kitchen to a lavatory.(=Many kinds of clean energy are converted into electricity, since they cause less environmental pollution.)CF: reform, convert & revise这三个词都是动词，都有“改良”、“改变”之意。

To solve an equation means to find the value of the unknown term. To do this , we must, of course,change the terms about until the unknown term stands alone on one side of the equation, thus making it equal to something on the other side. We then obtain the value of the unknown and the answer to the question. To solve the equation,therefore,means to move and change the terms about without making the equation untrue,until only the unknown quantity is left on one side ,no matter which side.解方程意味着求未知项的值，为了求未知项的值，当然必须移项，直到未知项单独在方程的一边，令其等于方程的另一边，从而求得未知项的值，解决了问题。

因此解方程意味着进行一系列的移项和同解变形，直到未知量被单独留在方程的一边，无论那一边。

Equation are of very great use. We can use equation in many mathematical problems. We may notice that almost every problem gives us one or more statements that something is equal to something, this gives us equations, with which we may work if we need it.方程作用很大，可以用方程解决很多数学问题。
